Fix a TypeScript code generation edge case (#3199)
This release fixes a regression in version 0.18.4 where using a TypeScript namespace that exports a class declaration combined with --keep-names and a --target of es2021 or earlier could cause esbuild to export the class from the namespace using an incorrect name (notice the assignment to X2._Y vs. X2.Y):
// Original code
// Old output (with --keep-names --target=es2021)
var X;
((X2) => {
const _Y = class _Y {
};
__name(_Y, "Y");
let Y = _Y;
X2._Y = _Y;
})(X || (X = {}));
// New output (with --keep-names --target=es2021)
var X;
((X2) => {
const _Y = class _Y {
};
__name(_Y, "Y");
let Y = _Y;
X2.Y = _Y;
})(X || (X = {}));
v0.18.10
Fix a tree-shaking bug that removed side effects (#3195)
This fixes a regression in version 0.18.4 where combining --minify-syntax with --keep-names could cause expressions with side effects after a function declaration to be considered side-effect free for tree shaking purposes. The reason was because --keep-names generates an expression statement containing a call to a helper function after the function declaration with a special flag that makes the function call able to be tree shaken, and then --minify-syntax could potentially merge that expression statement with following expressions without clearing the flag. This release fixes the bug by clearing the flag when merging expression statements together.
Fix an incorrect warning about CSS nesting (#3197)
A warning is currently generated when transforming nested CSS to a browser that doesn't support :is() because transformed nested CSS may need to use that feature to represent nesting. This was previously always triggered when an at-rule was encountered in a declaration context. Typically the only case you would encounter this is when using CSS nesting within a selector rule. However, there is a case where that's not true: when using a margin at-rule such as @top-left within @page. This release avoids incorrectly generating a warning in this case by checking that the at-rule is within a selector rule before generating a warning.
v0.18.9
Fix await using declarations inside async generator functions
I forgot about the new await using declarations when implementing lowering for async generator functions in the previous release. This change fixes the transformation of await using declarations when they are inside lowered async generator functions:
// Original code
async function* foo() {
await using x = await y
}
// Old output (with --supported:async-generator=false)
